TBU-CA085-500-WH is a TBU-CA series TBU® high-speed protector. It is low capacitance single bidirectional high-speed protection components, constructed using MOSFET semiconductor technology, and designed to protect against faults caused by short circuits, AC power cross, induction and lightning surges. The TBU® high-speed protector placed in the system circuit will monitor the current with the MOSFET detection circuit triggering to provide an effective barrier behind which sensitive electronics will not be exposed to large voltages or currents during surge events. Application includes voice / VDSL cards, protection modules and dongles, process control equipment, test and measurement equipment, general electronics.
